IMPROVEMENT IN THlLL-COUPLINGS.

Specification forming part of Letters Patent No. 208,400, datedSeptember 24, 1878 application filed June 26, 1878.

' to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the construction of a clip forsecuring shaft-irons to vehicles, as also in the construction of the pinor bolt which is used in connection with same, as will be hereinaftermore particularly described.

To enable those skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

In the accompanying drawings, making part of this specification, Figurel is a plan View; Fig. 2, a side view, and Fig. 3 a section in line ofthe shaftiron.

In the figures, A represents the axle of a vehicle; B, the clip, and G Gthe arms of said clip 5 F represents the shaft-iron, and D representsthe pin or. bolt which connects the shaft-iron to the arms of the clip.

The parts are made in the ordinary manner, except as follows: The boltis made with a hooked end, E, at its head, having upon it a shoulder, a.The end of the shaft-iron has the opening cut through it to receive thebolt in such manner that the metal will be thinner on one side than theother, as seen at m, Fig. 3. ()nc arm of the clip is formed in a similarmanner, the metal being thinner upon its upper side than upon its lower,at the point where the opening is formed to receive the bolt, as seen aty, Fig. 2. The hook upon the bolt is made just long enough so that itsshoulder at a will catch on the inner face of one of the arms. When theshaft-iron is raised to almost a perpendicular position, the thin sideof the shaft-iron and the thin side of the clip-arm are in line or inclose proximity. In this position the bolt is inserted, and then, as theshaft is lowered into ahorizontal position, the bolt-head catches uponthe clip-arm and is there retained.

It will readily be seen that the moment the two thin portions of the armand the shaftiron change positions the bolt cannot be removed, and notuntil they assume the same positions again. This is a cheap and securefastening.

I Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the shaft-iron F, with reduced portion, a, clip B,and arms 0 O, having the reduced portions y, and the bolt D, with hookedhead E, having the shoulder a, all substantially as and for the purposesherein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this20th day of May, 1878.

AMOS E. KIMBERLY.
